I have a complete 300c.i. with a 300 super tubine transmission. I took it out of 67 Special a couple of years ago to install a 455. The engine has 100256 miles on it and I put the last 33000 on it. I drove the car 1 day before dismantalling it and the engine/trans ran like a top! It is complete from carb to tailshaft ,even the exhaust manifolds. You can reach me at BAD67GS@aol.com . I'm in Ohio. Thanks, Gary
